Physical properties and structure of glass medium QS-P2O5-CaO-BaO-Gd2O3/GdF3 doped Dy3+

ABSTRAK

Optical glass medium derived from local natural resources, namely Huta Ginjang quartz sand was successfully synthesized using the melt-quenching method at a temperature of 1200°C. The chemical composition of the glass was arranged in the main formulation of 15QS + 59.5 P2O5 + 5 CaO + 10 BaO + 5 Gd2O3/GdF3 + 0.5 Dy2O3 with active ion doping Dy3+ at a concentration of 3 mol%. The main difference between the two samples lay in the substitution of Gd2O3 with GdF3 which produced two types of samples with different characteristics. After the initial stage of formation, the samples were cut and polished to obtain precise dimensions and the appropriate level of transparency. Characterization tests included measuring density, molar volume and ion concentration based on the Archimedes principle as well as numerical calculations. Structural analysis was carried out using Fourier transform infrared spectroscopy (FTIR) to identify the constituent functional groups and X-ray diffraction (XRD) to ensure the amorphous nature of the glass medium. This research was conducted to develop locally sourced phosphate glass materials as potential candidates for optical media applications in photonics technology.
